.SH "NAME"
bugle-stats_fragments \- gather fragment counts
.SH "SYNOPSIS"
.sp
.nf
filterset stats_fragments
.fi
.SH "DESCRIPTION"
.PP
The
stats_fragments
filter\-set provides signals for the number of fragments to other filter\-sets\&. It must be listed in a chain that uses any statistics related to fragment counts\&.
.PP
It is simply a wrapper around
GL_ARB_occlusion_query, so a
fragment
is defined exactly as in that
\m[blue]\fBextension\fR\m[]\&\s-2\u[1]\d\s+2
(and OpenGL 1\&.5), and will not work unless that extension is supported\&.
.SH "BUGS"
.PP
Fragment counting will not work in applications that use occlusion queries\&. A warning is displayed when this is detected\&.
.SH "AUTHOR"
.PP
bugle
is written and maintained by
Bruce Merry\&.
